I am currently dealing with a “package is in a very bad inconsistent state - you should reinstall it before attempting configuration.” problem. It is due to a faulty installation of wolfram-engine.
As far as I know, PiPlay is meant to be a distribution that focuses on emulation :) Is the Wolfram Engine really necessary? The install package takes up close to 500 MB (not counting any possible dependencies) and it seems dumb to bloat a distribution meant to be run on perhaps small 4 GB sd cards.
Is Wolfram Alpha just something leftover from the Raspbian distro?
the PiPLAY image is not a minimal one, it is just the defaults Raspbian plus PiPLAY addition on top. so all un-necessary crap like wolfram-engine, scratch, sonicPi, and so on is still there.
wolfram engine has non positive and non negative influence to piplay... it is just there and steals diskspace... and in case of upgrading, it takes a lot of download and upgrade time...
sure, you can purge/remove it... there is no need for wolfram emgine.
